Embodiment Construction

[0046] like Figures 1 to 3 Shown, be a kind of decentralized sewage treatment method of the present invention, comprise the steps:

[0047] (1) Construction of regulating pool

[0048] a. First determine the construction area according to the design requirements, and use an excavator to excavate to the set depth in the corresponding construction area to form the adjustment pool 1, then tamp the sides and bottom of the adjustment pool 1, and then pour concrete. The pouring thickness is 10-15cm;

[0049] b. After the concrete reaches the set strength, set up reinforcement bars inside the regulating tank 1, and then install the second water delivery pipe 12 in the regulating tank 1, so that the port of the second water delivery pipe 12 and the bottom surface of the regulating tank 1 The spacing is less than 25cm, and a water pump 13 is installed on the second water delivery pipe 12, and then the second water delivery pipe 12 is fixed on the inner side of the regulating tank 1;...

Abstract

The invention discloses a distributed type sewage treatment method which comprises the following steps: (1) constructing a regulating reservoir; (2) constructing an anoxic pond; (3) constructing a membrane biological reaction pond; (4) constructing a sludge tank and a reclaimed water pool; and (5) treating the sewage. The sewage treatment method disclosed by the invention is simple in steps, not only can reduce the pressure of urban centralized pipeline sewage treatment but also directly utilizes the reclaimed water acquired after the treatment, effectively protects the water resource, reduces the operation cost and is convenient for management and maintenance.

Description

technical field [0001] The invention relates to a decentralized sewage treatment method. Background technique [0002] Decentralized sewage treatment refers to the adoption of a new and complex approach to meet the requirements of wastewater management and resource utilization in small-scale areas, which allows individual small-scale sewage treatment and on-site soil treatment systems as long-term solutions. [0003] The decentralized sewage treatment in the prior art simply filters the sewage and cannot realize the reuse of reclaimed water, which easily causes waste of water resources, and the maintenance and management are cumbersome. Contents of the invention [0004] The purpose of the present invention is to provide a technical scheme of a decentralized sewage treatment method for the deficiencies in the prior art, which not only reduces the pressure of urban centralized pipe network sewage treatment, but also can directly utilize the reclaimed water obtained after tr...
